This is correct. I logged in and I am missing basically any of the cosmetic stuff that say “sometimes in the shop” were taken off my account and are now locked (Like wave racer Dva, poolside ashe, etc.).
I think what happened may be they accidentally caused anything that is unlockable in the “shop” to become locked on your account from OW1 even if it was unlocked already. I had pretty much every cosmetic unlocked from playing OW1 so much (except stuff from the last year). I hope it gets fixed as I know this is a way bigger deal for other people. Feel free to check my account as well for reference if needed.
EDIT: It seems after about 3 hours (currently 6PM EST) everything is showing updated and I have all my cosmetics now.
